[0002] A reducing elbow, also called a reducer elbow, is a pipe fitting that connects two pipes with different diameters and turns. The diameter changes at the bending part, thereby realizing the reduction or expansion of the pipe diameter. Reducing elbows are widely used in pipeline systems in industries such as chemical engineering, petroleum, pharmaceuticals, and water supply and drainage. They play an important connecting role where the pipeline layout needs to change the pipe diameter and direction. In short, reducing elbows play an important role in pipeline systems. They can meet the connection and turning requirements between pipes with different diameters, providing convenience for the design and installation of pipeline systems.
[0003] The existing reducing elbows usually adopt an integral pipe, and both ends are connected to other pipes through connecting components. The reducing elbow is generally used as a pipe fitting for making a 90° turn in the pipeline. Using an integral pipe cannot adjust its bending angle, and the bending angle is fixed, which is not convenient to use. Summary of the Utility Model

[0031] Embodiment
[0032] As Figure 1 shown, a reducing elbow that is easy to disassemble and assemble according to the present utility model includes a reducing elbow body 1. The reducing elbow body 1 includes a first pipe head 2 and a second pipe head 3. One end of the first pipe head 2 is connected to one end of the second pipe head 3 through a bending assembly. The bending assembly has a bending angle adjustment function and can adjust the bending angle at the connection of the first pipe head 2 and the second pipe head 3, facilitating the connection of pipes in different directions and making it more convenient to use.
[0033] As Figure 2 、 Figure 4 、 Figure 5 shown, the bending assembly includes a bending pipe 4 and a corrugated shell pipe. The corrugated shell pipe covers the outside of the bending pipe 4. One end of the first pipe head 2 and one end of the second pipe head 3 are both provided with connection shells 6. Two ends of the bending pipe 4 are respectively inserted into the connection shells 6 of the first pipe head 2 and the second pipe head 3. The bending pipe 4 is made of rubber material, and the bending pipe 4 is adhesively connected to the connection shell 6. Two ends of the corrugated pipe 5 are respectively adhesively connected to one end of the first pipe head 2 and one end of the second pipe head 3 through rubber rings. Using rubber for the bending pipe 4 can not only be bent arbitrarily, but also achieve better sealing performance and reduce the possibility of water leakage. Covering the bending pipe 4 with the corrugated pipe 5 can not only protect the bending pipe 4, but also does not affect the adjustment and change of the bending angle of the bending pipe 4.
[0034] As Figure 3 、 Figure 6 、 Figure 7 shown, the other ends of the first pipe head 2 and the second pipe head 3 are both connected to the pipeline through connection plates 7 with disassembly functions. The other ends of the first pipe head 2 and the second pipe head 3 are both provided with threaded pipes 8. A threaded hole is provided in the center of the connection plate 7, and the threaded hole of the connection plate 7 is locked and connected to the threaded pipe 8 through threads. Limit blocks 9 for restricting the movement of the connection plate 7 are provided on both the first pipe head 2 and the second pipe head 3. A sealing rubber ring 10 is provided on the mutually connected surface between the connection plates 7. A number of connection holes 13 for connection are correspondingly provided on the connection plate 7 and the sealing rubber ring 10. A locking bolt 11 is provided in the connection hole 13, and the connection plates 7 are connected through the locking bolt 11 and the nut 12. The connection plate 7 can be customized according to different pipelines and is directly tightened by threads, making disassembly and installation convenient. The sealing rubber ring 10 can further improve the sealing performance at the connection between the first pipe head 2, the second pipe head 3 and the connected pipeline.
[0035] During use, first install the two connecting plates 7 onto the first pipe head 2 and the second pipe head 3. The limiting block 9 limits the connecting plates 7, making the outermost circumference of the connecting plates 7 protrude from the end faces of the first pipe head 2 or the second pipe head 3. Then install the connecting plates 7 on the connected pipes, and successively connect the first pipe head 2 and the second pipe head 3 to the connected pipes through the connecting plates 7. The adjacent connecting plates 7 are locked by the locking bolts 11 and nuts 12. During the installation process, the bending angle between the corrugated pipe 5 and the bent pipe 4 can be adjusted, so that the reducing elbow body 1 is adaptively connected to the pipe to be connected.
[0036] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that they can still modify or equivalently replace the technical solutions of the present invention, and these modifications or equivalent replacements cannot make the modified technical solutions deviate from the spirit and scope of the technical solutions of the present invention.
